SCM sale, maybe the ~40k sale on Jan 5?

But dumped in bulk a day later for arcana t. tyrolean, so maybe high anyway:

https://steamcommunity.com/market/listings/440/Unusual%20Optic%20Nerve (sale had to have ben between Dec 27-28)

This is most likely the ~26k sale on Dec 28, as the Dec 27 sale is MUCH lower than buy orders (like basically ~10k)

arthur said he sold for 50k, which would make sense given the peace sign modest dumped the same day from buyer's end

I think I missed this initially (was in-date at time of original suggestion):

https://marketplace.tf/items/tf2/31224;5;u200

https://manic.tf/keyprice/?at=2021-12-10&price=79.99

$79.99 / $1.83 = 43.71 keys

Sales:

10? (low), 26, 40 (dumped), 44, 50

Going 26-50 given 44-50 would probably be too lopsided.
